Recently, the Abu Dhabi International Petroleum Expo (ADIPEC) came to a successful conclusion. Jiangsu Shenlida Machinery Manufacturing Co., Ltd. showcased its core oil and gas equipment products such as screw fasteners, disassembly frames, and power pliers, demonstrating the hard core strength and professional service capabilities of "Shenlida Manufacturing" to global customers. It also conducted in-depth exchanges with overseas customers, held closed door negotiations with more than 30 target customers and partners, reached procurement intentions with 12 Middle Eastern oil and gas developers, and signed regional agency cooperation memorandums with more than 100 distributors in North America, Africa, and other regions. The United Arab Emirates, as an important oil and gas resource country in the Middle East, provides a strategic pivot for the company's overseas layout due to its stable business environment and advantageous location radiating to the Middle East and Africa. This exhibition not only enhances the brand influence of Jiangsu Shenlida in the Middle East market, accurately reaches target customers in the Middle East, and effectively promotes core products such as screw fasteners, disassembly racks, and power pliers to go global, but also accelerates the technological innovation and iterative upgrading of related products through in-depth exchanges with global peers on the trends of intelligence and low-carbon technology.Jiangsu Shenlida's participation in this exhibition is an important member of the domestic oil and gas equipment industry cluster exhibition group. Its core products, such as screw fasteners, disassembly racks, and power pliers, have become key recommended categories by the exhibition group due to their adaptation to the high-intensity operational needs of the Middle East oil and gas extraction scene. Jiangsu Shenlida's twisting machines, power pliers, and other products have become key negotiation targets for overseas customers due to their stable adaptability to working conditions.

Bucking units are critical equipment in drilling operations, and their parts inevitably wear out under long-term, high-load, and high-frequency operating conditions. Part wear not only affects the proper operation of the equipment but can also degrade connection quality and even cause safety incidents. Therefore, scientific and rational replacement of worn parts is crucial to maintaining the performance and operational safety of the bucking unit. The following details the replacement procedures and precautions for worn bucking unit parts.1. Identification and Determination of Worn PartsBefore replacement, it is important to accurately identify and determine which parts are worn and require replacement. Common worn parts include jaw gaskets, hydraulic cylinder seals, oil seals, bearings, guide rails, and fasteners.Visual Inspection: Observe the surface of the parts for obvious scratches, cracks, deformation, or defects.Functional Testing: Problems such as sluggish operation, weakened clamping force, and hydraulic leakage during operation often indicate severe wear of the relevant parts.Dimensional Measurement: Measure the dimensions of key parts using specialized tools to determine whether they exceed the wear limits specified by the manufacturer or industry. Lubrication: Check the lubricating oil for metal shavings or unusual contaminants. If present, this may indicate increased wear on internal parts.After identifying worn parts, a replacement plan should be developed promptly to prevent further damage.2. Preparatory Work Before ReplacementShutdown and Power OffEnsure the Bucking Unit is completely stopped. Disconnect the hydraulic system power and electrical control power to prevent accidental startup.Clean the Work EnvironmentRemove oil and dust from the equipment surface. Keep the work environment clean and tidy to facilitate observation and subsequent operations.Tool and Spare PartsPrepare required specialized disassembly and assembly tools, screwdrivers, wrenches, etc., and ensure that replacement parts are from legitimate sources and of the correct model.Technical Data ReviewRefer to the equipment manual or service manual for disassembly and assembly procedures, precautions, and torque specifications.3. Disassembly Procedures for Wear PartsDepressurization and Oil DrainingBefore replacing hydraulic system parts, release system pressure to prevent hydraulic fluid from spraying out and injuring personnel. Drain the hydraulic fluid completely if necessary to prevent environmental contamination.Removing External AccessoriesFirst, remove external connectors associated with the worn parts, such as pipe joints, mounting bolts, and protective covers. Disassembling Main PartsAccording to the maintenance manual, use specialized tools to remove worn parts. Handle with care to avoid secondary damage to surrounding parts.Inspecting Removed PartsPerform a detailed inspection of the removed parts to determine the wear condition and cause, which will guide subsequent repair or replacement.4. Installation Procedure for New PartsCleaning the Installation AreaBefore installation, thoroughly clean the part mounting seat and related mating surfaces to ensure they are free of oil, impurities, and rust.Inspecting the Condition of New PartsConfirm that the new parts are intact and of the correct specifications and model. Apply any necessary lubrication, such as rust-proof oil or grease.Precise Installation and PositioningAccording to the drawings or technical specifications, accurately position the parts to avoid eccentricity or misalignment.Tightening Bolts and ConnectorsTighten the relevant bolts gradually and evenly according to the manufacturer's specified torque standards to ensure a secure connection without deformation.Installing Hydraulic SealsSeals, oil seals, etc. should be installed gently to avoid scratching or stretching. Use specialized installation tools if necessary.Replacing Disassembled AccessoriesRestore removed piping, protective covers, etc. to ensure the structural integrity of the equipment.5. Post-Replacement Inspection and CommissioningCheck SealingStart the hydraulic system and inspect the replaced parts for oil leaks or seepage.Functional TestPerform no-load and loaded test runs to verify smooth operation and normal clamping force.Check Operating ParametersMonitor key parameters such as oil pressure, temperature, and torque to ensure they are within normal ranges.Observe for Abnormal Sound and VibrationAfter replacement, there should be no abnormal noise or vibration. If any abnormality is detected, shut down the machine for inspection immediately.6. Precautions for Replacing Worn PartsSelect Qualified PartsPurchased parts must meet equipment specifications. Avoid using inferior or incompatible substitutes.Take Protective MeasuresWear protective gear during disassembly and installation to prevent oil splashing and mechanical damage.Record Maintenance InformationDetailed records of part replacement time, specifications, reasons, and operating status will facilitate equipment management and lifespan assessment.Avoid Reusing SealsOnce removed, seals should not be reused to ensure effective sealing.Environmental ProtectionDisposal of waste oil and used parts must comply with environmental regulations to prevent contamination.SummaryBucking unit part wear is an inevitable part of normal equipment operation. However, through scientific identification, standardized disassembly and assembly, replacement of high-quality parts, and rigorous commissioning and testing, equipment performance can be maximized and service life extended. A well-planned parts replacement cycle, combined with routine maintenance and management, can effectively reduce failure rates and ensure the continuity and safety of drilling operations. While replacing worn parts is a tedious task, each meticulous step is fundamental to ensuring stable equipment operation and must not be neglected.
